Do I need a permit for window or exterior door replacement in Plainfield?
Most likely yes. Window or exterior door replacement usually requires a permit in Illinois. Confirm the specifics with Plainfield.
Illinois publishes no statewide list of work exempt from a residential building permit. Most Illinois jurisdictions treat a like-for-like window or door replacement in the same opening as exempt, while enlarging or adding an opening triggers a permit and structural (header) review. Confirm the local rule before you order units. Many local codes require bedroom windows to meet emergency escape and rescue (egress) sizing when they are replaced, under whichever residential code edition the jurisdiction has adopted. The Village of Plainfield enforces the 2021 International Residential Code, which governs egress, safety glazing, and structural openings, so replacing windows or exterior doors generally needs a permit, especially when an opening is resized or a header changes. The Village publishes a Before You Build siding guide and reviews exterior alterations, so confirm your specific window or door scope with the Building Department at 815-439-2937 or building@goplainfield.com before ordering materials. Apply through the Village Permitting and Licensing Portal at plainfieldil.viewpointcloud.com, and note that a contractor performing the work must register annually with the Village and carry the required bond and insurance. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
